) Man technology sure has come a long way. I was soooo happy when I got them on and walked around the house that I kept them on while we stood in the kitchen and prepared dinner. Other was to eliminate the whistle get a long bungy cord wrap across, or get some metal duct tape put across the bottom and cut to fit. Arrived fine, well packed, as represented. Great headphones, I enjoy the sound. one time out really???? So 2 stars ?? ?? Now! Functions well. It?s materials are heavy duty. Whether it?s for gaming, listening to music or taking calls Ive found its performance to be excellent and reliable for a headset in this price range. Yo he comprado con Razer en repetidas ocasiones en otras paginas y a diferencia de muchos, jamas me han decepcionado y siempre he quedado satisfecho con sus productos, lo digo en serio.
